On the south, east and west, these ranges, though wild and rugged, are of no great elevation, but on the north the Pyrenees attain their greatest altitude in the peaks of Aneto (11,168 ft.) and Monte Perdido (10,998 ft.) - also known as Las Tres Sorores, and, in French, as Mont Perdu.
Marcel Proust, In Search of Lost Time The performance A la recherche du temps perdu takes the code literally.
Proust 's A la recherche du temps perdu published.
On the Spanish side, from north to south, are (1) the zone of Mont Perdu, Upper Cretaceous and Eocene; (2) the zone of Aragon, Eocene; and (3) the zone of the Sierras, Trias, Cretaceous and Eocene.
In both ranges, too, some of the highest summits stand on spurs of the main range, not on the main range itself; as Mont Perdu and Maladetta lie south of the main backbone of the Pyrenees, so Mount Elbruz and Kasbek, Dykh-tau, Koshtan-tau, Janga-tau and Shkara - all amongst the loftiest peaks of the Caucasus - stand on a subsidiary range north of the principal range or on spurs connecting the two.
